Salvaging a print

Recommended Posts

Posted · Salvaging a print

I've been intrigued with saving a print-gone-wrong since I started using the Ender last December.  Right away I came across M27 and M26 that use the Byte Offset of the print position in a file.  I got Micorsoft Excel to talk to the printer and by crunching a gcode file with some Visual Basic macros, I figured it out. 


I started printing Mrs. Rabbit as a conventional slice with infill and wondered what would happen in Vase mode.  So I aborted the print and had Excel send an M27 to get the byte offset and then the XYZE locations, sliced the Jessica file in vase mode and was able to justify the byte location within the new file, used M26 to jump to the byte offset in the new file and used a G92 to synchronize the extruder, and regular G moves to get the XYZ synced in and it worked very well.  Off course she has some.......interesting.......horizontal parts that don't do well in vase mode, but what the heck.  An experiment is an experiment.


She would be impossible to print completely in vase mode since the model is standing on a flat raised dais.  The file with infill handled the platform (and part of her feet) as you can see in the second image.  The last image shows the area of the seam from the other side and not backlit.  Even with the print in my hand I can't tell exactly where one file stops and the other starts.


I am officially pleased with myself for figuring this out (even if I do feel a bit like Igor).  Mrs. Rabbit appears courtesy of Thing-i-verse and she will be on a pedestal that proclaims "I'm not bad.  I'm just drawn that way."

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
